针对基于位置的容迟容断网络(DTN)路由算法进行深入研究,提出一种适用于三维部署环境的基于位置的功率感知路由算法(3DPLRP),该算法利用节点三维位置信息寻路,大大降低了网络开销,此外因功率感知机制的引入延长了网络生命周期.在不同网络环境下与Epidemic、PREP路由算法进行了比较,仿真实验结果表明,3DPLRP在节点移动速度不高的情况下消息投递率和端到端时延等性能均要优于其他路由算法. Aiming at the DTN routing algorithm based on location, this paper proposes a location-based power-aware routing algorithm (3DPLRP) which is suitable for 3D deployment environment. This algorithm uses the three-dimensional location information of nodes to find a way and greatly reduces In addition, the network life-span is prolonged due to the introduction of power-aware mechanism, which is compared with Epidemic and PREP routing algorithms in different network environments. The simulation results show that when 3DPLRP moves slowly, the message delivery rate And end-to-end delay are better than other routing algorithms.
